Which ITR for STCG and professional income

File ITR 4 and declare the gain in other income..

Thank you sir. Will do as advised.

Good luck..                         

Thank you sir. One more query i have. I earn rent from my house property which is a joint ownership with my wife and I file IT return for her also. 

Should I show only 50% of the rent received under rental income on my ITR or full amount? 

If you rental agreement specified both as owner, then divide the rent as per your shares of ownership.

Thanks. Yes I am doing that only @ 50% of share to each of us and will show the other 50% in her return under rental income

That's correct procedure.           

The AO can ask for the source of funds for joint ownership. They always look for clubbing the income . So keep all the supporting evidences and bank statements showing source of funds by you and your wife 

Best wishes
